UNITED STATES PATENT WAGON-AXLE.

SPECIFIGATION'forming part of Letters To all whom it may concern:

7 act description.

Be it known that I, ANDREW KIMBLE, of Moundsville, in the county ofMarshall and State of West Virginia, have invented certain new anduseful Improvements in Wagon-Axles, of which the following is a full,clear, and ex- This invention consists in certain combinations, with awagon-axle and with the bolster and bound thereof, of a truss-bar turnedup at its outer ends and secured in position, to

gether with the skeins on the axle, by end screws passing into the axle,also connected by bolts and tightening-nuts with the holster, bound, andaxle, substantially as hereinafter described, whereby the axle isrestrained from upbreak and the truss-bar-from becoming loose at itsends.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a longitudinal side view of a wagon-axle and bolsterwith the trusshar, bounds, and certain fasteniugs applied, all inaccordance with-my invention, one of the skeins on the axle and screwused to hold it and truss'barin place being removed. Figs. 2,3, and 4:are views, upon a larger scale, of the same in part, Fig. 2 being atransverse section on the line in Fig. 1'; Fig. 3, a longitudinalsection on the line y y in Fig. 2, with the skein applied; and Fig. 4, atransverse section on the line 2 z in Fig. 1;

A in the drawings indicates the bolster, B the axle, and U the hound, ofav wagon.

Dis the truss-bar.

E E are bolts arranged to pass through the bolster, hound, and axle,also through the truss-bar. Nuts 12 b are fitted on these bolts on theunder side of the axle to hold the bolster, hound, and axle together,and outside of these nuts on said bolts, between the axle and thetruss-bar, are fitted other nuts,

Patent No. 274,341, dated March 20, 1883.

Application filed December 28, 1882. (Modem extreme outer ends, a, areturned up over the ends of the axle in such manner or to such an extentas will admit of the skeins F fitting over them and the end portionsgenerally of the truss-bar. The turned-up ends a of the truss-bar areperforated to receive through double purpose of holding on the skeins Fand the truss-bar to its place.

This construction and combination of parts has many advantages overothers'for a like purpose. Thus it is superior to other arrangements inwhich a truss-rod applied to the axle is arranged to penetrate the axlefrom its under side to an extent that will weaken it, resting on blockswithin the axle, and to pass out through the center of each end of theaxle, where a nut is screwed onto it to hold on the 'skein and totighten the truss-rod. Under such previous arrangement, in order totighten the skeins and truss-rod, the nuts on the ends of said rodrequire to be screwed up so close or hard that not only are the threadson the ends of the truss-rods liable to strip and the nuts to come off,but the axle is liable to break in an upward direction almostimmediately inside of the inner ends of the skeins when the wheel of thewagon to which the axle is applied strikes an obstacle in its path. Thisis avoided by my construction and combination of parts.

'Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- I 1. The combination, with the bolster A,the

axle, and truss-bar, and provided with the nuts b c d, the nut b beingon the under side of the axle and the nuts 0 d on opposite sides of thetruss-bar, substantially as herein shown and described.

The combination, with the bolster A, the hound O, and the axle B, ofthe truss-bar 1), having turned up outer end portions, 0, the bolts E,passing through the bolster, hound, axle, and truss-bar, and providedwith the nuts b c d, the skeins F, and the screws f, substantially asherein shown and described.
